Epeoloides pilosulus (also sometimes referred to as Epeoloides pilosula), or the macropis cuckoo bee, is a species of kleptoparasitic (cuckoo) bee within the family Apidae. They are found in moist habitats along swamps, streams, and ponds near the nest aggregations of their Macropis (oil-collecting bee) hosts. They are considered a very rare and possibly endangered species with sparse observations across the Central and Eastern United States and Canada.
